Earlier reports said she was in critical condition, but police later said her injuries were not life threatening. Two other people were taken to the hospital for stress-related conditions.

The victim was working at Florida Builder Appliances when she was attacked.

Cohen said a second man, whose identity was not released, was in the car with Murray, 27, and went into the building with him. He said both show up on surveillance video, which was not immediately released.

"Both of them may have entered the business, but Murray was the gunman," Cohen said.

Deputies found the car outside a nearby grocery store, sheriff's spokeswoman Keyla Concepcion said. They charged at the vehicle with gun drawn, but officers opening its doors and trunk found no one.

Florida Builder Appliances sells kitchen appliances, according to its Web site. Manny Lavernia, the branch manager at another store in Miami, said the company did not want to comment.
